In short Qmail is completely modular. The checkpassword you choose is entirely
dependent on which method of authentication you wish to use:
/etc/password
plaintext password file (other than /etc/passwd)
LDAP
cdb password file
Mysql Database
Radius
etc
etc
In setting up "qmail-pop3d" you need to understand that qmail-pop3d provides
nothing more than the POP3 functions to operate on a users Maildir - it does
not collect useranem/password or arrange the authentication of the user.
Qmail operates as a sequence of programs doing their thing then running the
next program in the chain, e.g. you could setup the following scenario:
Using Daemontools, and the UCSPI packages you may wish to launch the
qmail-pop* system from tcpserver (which listens on port 110), further you
may wish to run tcpserver under a supervisory process, so the execution
"string" would be something like:
echo "Starting POP3 daemon."
/usr/local/bin/tcpserver -v -p -lmail.mydom.net -t2 -u 888 -g 888 0 110 \
/var/qmail/bin/qmail-popup mail.mydom.net \
/var/qmail/bin/checkpoppasswd \
/var/qmail/bin/qmail-pop3d Maildir 2>&1 | \
/var/qmail/bin/splogger pop3d &
The only real variable in this is getting your checkpasswd/checkpoppasswd
functioning - advice on testing your checkpasswd is available on www.qmail.org
